[Pkg-alsa-devel] Bug#369302: libasound2: ALSA lib control.c:816:(snd_ctl_open_noupdate) Invalid CTL default (binary patch)

[Markus Kammerstetter]

Package: libasound2
Version: 1.0.11-6
Followup-For: Bug #369302


If you do not want to make a symlink (see Laurence J. Lane's solution), binary patching of
/usr/lib/libasound.so.2.0.0
also works just fine.

# make a backup
cp /usr/lib/libasound.so.2.0.0 /usr/lib/libasound.so.2.0.0.bak

# use a hexeditor
hexedit /usr/lib/libasound.so.2.0.0

# and modify the alsa.conf PATH string from

This solution is pretty unconventional (at least), but if you do not want to patch the (trivial) bug in the source, recompile and reinstall, this solution is pretty forward.
If the fixed package is available it will overwrite /usr/lib/libasound.so.2.0.0 and all traces of the dirty hack solution are gone ;)
